Public bug reported:
Hot-Undocking isn't performed properly on Dell D630,
neither while the system is running nor in standby mode (suspend to RAM)
A) Pushing the undock button while the system is running:
- the Undock-LED at the docking station only flashes short (goes off
and 1/2sec later on again).
- in syslog the undocking event is recognized (see syslog below)
- but after a while, the "kacpi_notify" process crashes (see syslog
below)
- then, the processor-load of "kacpi_notify" stays at 50%
- until the notebook is removed from the docking station
B) Undocking in standby mode:
- Undocking the system in standby mode (Suspend to RAM), and powering
off-docked,
- the X-Window-System will be locked (may be restarted in a virtual
terminal by restarting gdm)
- Even worse after redocking in standby agin: the USB ressources on the
docking station arn't recognized again.
- Otherwise, when redocking the running system, the system freezes often
Release: 8.04 "Ubuntu hardy (development branch)", but the problem also existed
on older Releases (Gutsy, Feisty)
Package: linux-image ?
